Display speed

When on ZXBox displays actuall speed of emulation in percent.

Invert Colors

Do you want inverted color palette? (can be usefull on grayscale targets)

Frameskip

How much frames to skip before display one. With frameskip = 0 ZXBox tries to display 50 frames per second. So if your player's LCD speed is less than 50 fps with frameskip 0 you can't get full speed of emulation. For example iPod Video's LCD framerate is about 36.5 fps, so with frameskip 0 you'll get 74% speed, because zxbox want's to display 50 frames per second but just waits for lcd to display frame. You can see LCD framerates at LcdFrameRate page.

Custom keymap

This menu allows you to map buttons to whatever possible supported by vkeyboard Spectrum buttons you want.

Hacking graphics

Screens of some targets can be too small for some games so they can became unplayable.
This is because screen scaling procedure to be as fast as possible just skips some lines and columns so that picture would fit the screen.
Using some utilities like Spectrum Graphics Editor you can hack graphics so games would fit theese screens better.

For example, here is a screenshot of Chuckie Egg running on iPod mini:
